1. In what way do think the people living in are not socially responsible than the people married and living in? 2. Who says what we are supposed to follow? 3. Live in does not mean, they are not going to marry? What is exactly wrong with it?
your entire paragraph misses the point of why you don;t support other than saying we are not supposed to follow.
4. What makes you think that people living in together do that only for physical pleasure? Who said that to you?
5. If marrying and living together is allowed, then can we marry more than 1 person and live in?
6. Why Hindu gods have more than one wife? I'm indian and Hindu. So don;t blame other people.
Based on your witting, it appears that you are well educated and well thought. With all due respect in that direction, I challenge you to prove your point and i can prove you wrong in every aspect and every reason you give.
